The former president of DocX LLC, a now-defunct subsidiary of Lender Processing Services (LPS), is expected to do prison time after pleading guilty to state and federal criminal charges related to the "robo-signing" scandal.

In pleading guilty to a federal criminal charge, Lorraine Brown, 56, of Alpharetta, Ga., admitted her role in a six-year scheme involving more than 1 million fraudulently signed mortgage documents, prosecutors said.
